It is entirely compliant with the MUTCD and in many cases, the MUTCD text was composed with the LightGuard Systems product development and testing in mind. The System utilizes a series of light emitting diodes (LED’s) in a durable housing embedded in the roadway which flashes, in a unidirectional manner, a warning to approaching motorists that a pedestrian is in or entering the crosswalk. The in-roadway LED warning signals are aimed down the motorist-viewing path of the approaching driver to allow the flashing lights to be easily seen by motorists along the full length of the un-obscured viewing approach path. The lights flash for a set period of time before automatically turning off. The System can be activated by a pedestrian pushing a button, or automatically when a pedestrian passes through an activation zone breaking an optical beam. It can be a stand-alone solar-powered System, or a conventional AC powered System with battery back up. The LightGuard System comprises the following components and all components must work in unison. 1.2 POWER SYSTEM A roadside, or pole mounted, cabinet contains all of the LED drive electronics and field wiring electrical interfaces. Both the AC & the ECP systems operate off a 12 VDC power supply from an AC line. The AC system can be energized from either 110V single phase or 220V two-phase power. The ECP can only be energized from 110V single phase. The Solar System operates off of 12 VDC battery power and is recharged during daylight hours from a Solar PV panel. Based on a typical installation, power usage is approximately 18 - 20 watts depending on the type of activation mechanism. Total energy consumed (in KWH) is dependent upon the number of light fixtures, the cross time duration, and the number of activations. Circuit breakers protect internal circuitry and field wiring. The Power Control Unit (PCU) available in the AC & Solar Systems is based on a high speed 8 bit embedded microcontroller utilizing a compiled machine control language. LGS proprietary software program provides effective, reliable operation allowing the user simple operation adjustments with a keypad and display (LCD). 1.3 IN-ROADWAY WARNING LIGHT (IRWL) SIGNAL HEAD The LightGuard System™ In-Roadway Warning Light signal heads are manufactured of high strength impact resistant materials. They are designed to be mounted onto a metal or composite base plate assembly that is permanently attached to the roadway. This allows for easy replacement of any IRWL that may become damaged, or inoperable, for any reason. 1.4 SYSTEM ACTIVATION; AUTOMATIC/MANUAL/CONTINUOUS/PROGRAM 1.4.1 AUTOMATIC - Bollards For AUTOMATIC activation, the System uses state-of-the-art electronic and software driven technology. The Smart Crosswalk™ automatic system is a dual break-beam system utilizing modulated infrared sensors housed in decorative posts, or bollards, at each side of the Page 2 ® LightGuard Systems Installation & User Manual (all rights reserved) crosswalk. Direction of pedestrian travel is detected and allows activation of the System only upon entry, not when exiting. Custom designed bollards currently house the drive electronics for automatic activation. They can be positioned up to 50 ft. (15m) apart. 1.4.2 MANUAL - Push Button or optional Key Switch operation A standard push button assembly (if installed) may be depressed if the pedestrian chooses to MANUALLY activate the System. Unlike existing signage, when the pedestrian pushes the button an “ON” response from the System is immediately visible via flashing LED lights above the words “CROSS WITH CAUTION”. As an added benefit, the PCU automatically monitors frequency and direction of use. Other activation options include pre-set on-off times or Key Switch activation with a set “on” time operation. Keypad functions allow for up to three (3) automatic on-off times for each day of the week. 1.4.3 CONTINUOUS – CONSTANT ON The Illuminated crosswalk system can be set for continuous flashing 24/7. This is NOT recommended for solar powered systems due to the continuous power drain affecting battery recharge. 1.4.4 PROGRAMMABLE – Pre-set on/off timer The Illuminated crosswalk system can be programmed to activate for a predetermined duration with 3 different start stop times up to 7 days per week. Refer to section 2.8.4.11 for instructions. 1.5 LED “ENHANCED” PEDESTRIAN CROSSING SYMBOL SIGN It is recommended that a new fluorescent-yellow-green color (FYG), diamond-shaped pedestrian crossing sign (W11A-2) with LED warning light modules at the “enhanced” flash rate, is installed with each System (FYG S2-1 or W66 type school symbol sign also available). The LED warning light modules are designed to flash in conjunction with activation of the System. This active LED pedestrian crossing sign enhances driver recognition of the System’s presence, especially in adverse weather conditions, and contributes to educating the motorist as to the meaning of the flashing array of in-roadway warning signals. The new W11A-2 sign, with the LightGuard embedded LED warning light modules, replaces the standard W-54 sign typically placed at the crosswalk site. 1.6 LGS COMPONENTS NEEDED FOR A TYPICAL SMART CROSSWALK™ (Typical Four Lane Roadway Crossing) ITEM QTY SYSTEM DESCRIPTION 1) 1 LightGuard Power Control Unit (PCU) This PCU is based on a high speed 8 bit embedded microcontroller utilizing a compiled machine control language.

A DPST 5A circuit breaker protects the both the Line and Neutral for single phase OR both Lines for two phase input. The AC power is transformed to 13.5 VDC via a 150W power supply. The 5A DPST circuit breaker is marked by the factory for both Line & Neutral, with one pole of the 5A DPST circuit breaker labeled “hot black” and the other labeled “neutral white”. For 2 phase operation, the label marked “neutral white” must be removed or otherwise placard over & the power supply switch must be reset to 230V prior to energizing the main 5A DPST circuit breaker on the back panel. The switch setting is normally factory configured for 115V & MUST BE RESET at time of installation for 2 phase 230V source. Refer to section 2.3.3 for switch location. A Solar powered system uses a minimum 75W Photovoltaic array providing DC power to the internal batteries. All branch circuits have their own independent circuit protection in the Electronics Enclosure. An ECP system uses 115VAC single phase as an energy source. A DPST 5A circuit breaker protects the both the Line and Neutral. The AC power is transformed to 13.5 VDC via a 150W power supply. 2.2 TYPICAL LIGHTGUARD SYSTEM® WIRING DIAGRAM NOTE: This is a reference diagram only, connections shown are not applicable to all installations.

Page 14 ® LightGuard Systems Installation & User Manual (all rights reserved) 2.8 POWER CONTROL UNIT (PCU) DESCRIPTION The PCU is based on a high-speed 8 bit embedded microcontroller utilizing compiled machine control language. A LightGuard proprietary software program provides effective, reliable operation allowing the user to make simple adjustments to the System parameters with a keypad and liquid crystal display (LCD). 2.8.1 TYPICAL POWER CONTROL UNIT (PCU) DRAWING 9 PIN D-SUB CONNECTOR LCD LCD ILLUMINATION ADJUSTMENT 1 2 3 A 4 5 6 B 7 8 9 C * O # D KEYPAD “PUSH TO TEST” BUTTON (ALT LOCATIONS) BOLLARD & BUTTON INPUT INDICATORS LEDs (2 rows) FUSES PCU SYSTEM ACTIVATION INDICATOR LED blinks when “Push to Test” button is pressed 2.8.2 POWER CONTROL UNIT (PCU) PARAMETER ADJUSTMENTS The PCU is preprogrammed with easily adjustable parameters. To operate the System manually flip all circuit breaker switches up to “ON” position. All functions are accessible from the keypad. A highcontrast liquid crystal display (LCD) provides easy read out of the settings. Pressing a key will display data, or a parameter, on the LCD. Some keys will access a list of parameters. If no change is desired, press the “#” key to escape or advance to the next parameter in that list. Pressing the “#” key can also escape from a partially entered value. Each parameter has a required number of digits. The required number must be entered or the number will default back to existing number. The POWER CONTROL UNIT (PCU) KEYPAD FUNCTIONS TABLE describes programming the PCU using the keypad and display. Generally when a menu is accessed using one of the numeric keys, the user must complete all entries within that menu before the PCU will accept other menu parameter inputs. In many cases, the # key will act as a “next” function advancing the menu without changing the existing parameter in program memory. There is no “escape” key to undo keypad entries. If a keypad error is made, the user must complete that function menu & then repeat that function menu with correct keypad entries. Page 15 ® LightGuard Systems Installation & User Manual (all rights reserved) Additional notes INITIATING THE SYSTEM – When the PCU is energized for the first time, a message should display on the LCD with instructions to contact LightGuard Systems Inc. for an ACTIVATION CODE. This code is used for both system installation tracking & warranty tracking purposes. CROSS TIME - Refer to local governing agency for System activation / crossing time. Cross time is set in seconds (PCU is pre-programmed with 20 seconds as a factory default). Cross time is entered in 2 digit increments using the numeric keypad. Typical cross time duration is based on pedestrians walking speed being 2 feet to 3 feet per second. Slower pedestrians require more time than faster pedestrians. A generic formula to compute a typical cross time is to divide the length of the crosswalk (width of the street) by either 2 or 3. Cross time should be set by the installer after observing pedestrian patterns. An example of a 60 foot long crosswalk: 60’ ÷ 2’ per second = 30 seconds FACTORY SETTINGS - The system is preset with a cross time of 20 seconds, the activation counts are set to Zero, & the date/time are set for PST, system default is Single Zone Mode. ACTIVATION COUNT DISPLAY - When the system is in Activation Count Display Mode (LCD shows the number of activations for either bollards or push buttons), the system is in “a sleep state”. System activation WILL NOT occur (IRWL will not operate) until the activation count display mode is toggled off by pressing either 1 or 3 on the keypad respectively (software version 1.4 & earlier). When using software version 1.5 & later, activation count display mode will end after 1 minute to allow normal operation. DOWNLOADING PCU MEMORY – PCU memory contains a limited number (approximately 65,000) of “date/time stamped” activation counts, diagnostics, & “power-up” events. The data is accessible using a computer connected to the appropriate port via RS232. Refer to addendum procedure for correct steps. This feature is available in software version 1.5 & higher. SYSTEM ACTIVATION DISPLAY – When the system has been activated, the LCD will indicate a countdown of the remaining cross time until the Enlighten1TM flashing sequence ends. This feature is compatible with software version 1.6.7 and higher. REMOTE COMMUNICATIONS – The PCU is designed for remote communication via the RS232 port. When operated in Terminal Mode, the remote terminal will echo many of the PCU LCD commands and text as well as some system diagnostics. Also while in Terminal Mode, the remote terminal keyboard will operate all of the PCU keypad functions. Refer to addendum procedure for remote connections. This feature is compatible with software version 1.7 and higher. SINGLE/DUAL ZONE MODE– The PCU is capable of supporting both Single & Dual Zone Modes (whether or not the peripheral hardware for the Dual Zone Mode is physically connected to the PCU). The system default on “power up” is Single Zone Mode. Each time power is recycled to the PCU, the system will revert to Single Zone Mode operation. If Dual Zone Mode is required, pressing the keypad 2 will toggle into Dual Zone Mode. Single zone can be re-selected either by pressing keypad 2 again or by cycling power to the PCU. The mode can be verified (displayed on the LCD) using the keypad *. Refer to Dual Zone Installation Manual Addendum for further information. This feature is available in software version 1.7 & higher.

It is designed for mounting into a base plate assembly that is permanently attached to the roadway. This allows for any in-roadway warning light fixture that may become damaged, or inoperable for any reason, to be easily repaired with a plug-in replacement. IN-ROADWAY WARNING LIGHT (IRWL) TYPE-9X ASSEMBLY General Performance Specifications Parameter Value Visibility ± 22.5° Horiz +10° Vert Operating Temp −20° to +80°C Operating Voltage DC Current @ 12VDC Avg Power Dissipation Luminous Intensity Material Housing Color 3.2 Typical Mounting Base Plate Compatibility SD-10C (composite) CHS-14 (steel) Available Models LGS-9X-1 (Red) LGS-9X-2 (Amber/Red) LGS-9X-3 (Amber) LGS-9X-4 (White) 9VDC to 15VDC 0.1 Amps 1.5 watts 252,000 mcd Polyurethane/Nylon Black MAJOR CONSIDERATIONS FOR LIGHTGUARD SYSTEM IRWL INSTALLATION There are a number of basic considerations when determining the location and alignment direction of each in-roadway module for any given installation site. These items should be considered during the installation procedure for the LightGuard in-roadway warning system. Be sure to have enough specified wire/cable, 2-part epoxy, and saw cut filler (loop detector type filler) ON SITE BEFORE BEGINNING INSTALLATION. Figure 1: Example of properly installed 10” composite baseplate Figure 1: Example of properly installed 14” baseplate in a snowplow region 3.2.1 DISTANCE OUTSIDE OF, AND AWAY FROM CROSSWALK STRIPES The installer should measure and be certain to keep the distance at least 18” from the outward edge of the crosswalk. In general, greater distances can be used without any noticeable difference to the motorist. However, no greater distance than 10 feet (3m) is recommended by MUTCD standards. If required by a specific circumstance, (i.e., grade or advance curve warning layout) placement may Page 21 ® LightGuard Systems Installation & User Manual (all rights reserved) necessitate an authorized deviation, using sound engineering judgment (thereby not conforming to MUTCD standards). 3.2.2 LOCATION OF EACH INDIVIDUAL IRWL MODULE Each IRWL should be located in a position that will be directionally visible to the approaching motorist from their viewing position at the wheel usually 200’ to 400’ (61m to 122m) in advance of the crosswalk, allowing sufficient time to recognize and react to the warning lights upon activation. When locating IRWL in the path of street sweeping equipment, caution should be taken to consider the proper location for minimizing possible cosmetic damage to the IRWL at the “curb and gutter” locations (on the approach sides) by avoiding the “skid paths” associated with this type of equipment. 3.2.3 PATTERN The pattern or layout should follow the recommended configurations that have been tested and proven effective for the type of crosswalk for which the system is being used. The MUTCD - Manual for Uniform Traffic Control Devices 2009 chapter 4N (http://mutcd.fhwa.dot.gov/htm/2009/part4/part4n.htm) defines the authorized use & application of IRWL. For best practice; one module on the outside travel lane edge of each parking lane or bike lane (stay out of bike/parking lanes), one module on the center divider lane or line, and one module in each travel lane approximately under the location of each vehicle’s license plate, (or centered between the tire paths of the travel lane). The “geographic” center of the lane may not be the appropriate location as vehicular traffic tends to travel “off center” of any given marked lane. The idea is to minimize the frequency of tire impact to the in-roadway modules by placing them outside of the predominant vehicle tire wear pattern. With a raised median strip, the module that is usually placed on the centerline or lane should be installed on the far left of the approach lanes next to the raised median curb or barrier. For maximum or higher level needs, an optional addition of one module on each lane delineation line may be considered. Placement should be in accordance with MUTCD. Examples showing optional & required placement for California MUTCD can be found via http://www.dot.ca.gov/hq/traffops/signtech/mutcdsupp/pdf/camutcddraftrev/4L.pdf. 3.2.4 AIMING POINTS The light beam view path of the modules should be determined by the local traffic engineer or responsible agency for the purposes of reaching the motorists viewing point 200’to 400’ (61m to 122m) in advance of the crossing (refer to section 3.7 for aiming and alignment). Generally, the layout provides for the modules in the approach travel lanes to be aimed straight down the approaching motorist’s viewing path. The parking lane units (from the left and right sides) should also be aimed or aligned toward a “control point” approximately 200’ to 400’ (61m to 122m) in advance of the crossing, and should also converge at the approaching motorist view path. This would have the outside units canted slightly inward toward the center of the lanes to that point. The units on the center line and opposing travel lanes will be canted slightly toward the approaching motorist travel lanes to those “control points” that will allow the approaching motorist the best view of the light source generally from 200’ to 400’ (61m to 122m) away depending upon the approach speeds at the particular location. Curved approaches will require a greater degree of analysis to provide the maximum benefit. 3.2.5 SAW CUT FOR WIRING AND IRWL MODULES The saw cut for wiring should follow the manual for depth and width to accommodate the necessary wiring and tray cable for the installation. As a general rule this averages ⅜”- ½” (9.5mm – 12mm) wide cut approximately 2 ½” (63mm) deep (should be below core drill depth). Operational component connections from PCU to across the street can be pulled to terminal boxes for easy access connecting activation mechanisms and other active LED components using standard type wire. Ensure that the saw cut makes a complete loop through all IRWL locations (refer to wiring diagram section 3.6.2). 3.2.6 DEPRESSION CUTS FOR LIGHT MODULE (IRWL / SIGNAL HEAD) BASE PLATES The depression cuts for the base plate assemblies can be accomplished in a number of ways. Most contractors prefer core drilling or a chip hammer. A flat bottom “Grinding Core Drill Bit” (section 1.7) is available to improve efficiency. Also, making “cross cuts” in the pavement at the IRWL location will Page 22 ® LightGuard Systems Installation & User Manual (all rights reserved) considerably expedite the core drilling process (refer to Figure 3 & Figure 4 for example of Grinding Core Drill & “cross cuts”). After determining the location and aiming direction of a particular light module, then core or chip out hole approximately 1⅜” ± ⅛” (35mm ± 3mm) deep refer to reference dimension table 3.2.6.1. A clean “corner” is desired at the bottom (flat bottom, vertical edges). Trim interior surface to proper depth, clean and prepare for epoxy. The size of the depression cut is VERY important. If the depression cut is too deep or the OD is too large, then excess epoxy will be required for securing to the roadway. If the depression cut is too shallow, the base plate will protrude above grade. If the depression cut OD is too small, insufficient epoxy will prevent the base plate from being permanently affixed to the roadbed.

AFTER ALL WIRES ARE IN PLACE IN THE WIRE CUTS, trim the wire to a suitable length to work with for wiring the base plates. Using duct seal or equivalent, create a temporary “epoxy dam” section 3.5.3 at the interface where the saw cuts enter/exit the depression cut area. The temporary epoxy dam prevents epoxy from flowing from the depression cut into the saw cut. Remove plastic thread protectors from threaded holes in base plate. Temporarily install socket head cap screws into threaded holes (approximately 3-4 turns) in order to use the screws for base plate leveling. Slip the wire through the center hole and “stand” the base plate on end “ready” to place into the depression. Thoroughly mix the appropriate type of epoxy for use in the base plate depression cut. Place an appropriate amount of 2 part epoxy in the depression (sufficient to completely seal bottom and rise around outside edges of the base plate when pushed into place). To insure a proper moisture seal, place the initial “glob” of epoxy in the center of the depression, move (or wiggle) wires around in the epoxy to attain wire seal, then push material to the outside edges and set the base assembly in place. The base plate should be aimed and level (use the temporarily installed screws to elevate the base plate if required during leveling) before epoxy is allowed to set-up properly. Note: If the depression is for some reason cut too deep, a “few” small rocks, pebbles or BB’s can be used to maintain a proper height. It is best to have the epoxy surround the base plate edges approximately level with the surface. Page 23 ® LightGuard Systems Installation & User Manual (all rights reserved) NOTE: Epoxy working life is approximately 10 minutes depending upon ambient temperature. After this duration, the base plate can’t be moved. Allow epoxy time to fully set, generally 20 to 30 minutes, prior to installing IRWL. 3.2.8 WIRES Be certain that wire (ref section 1.6) type RHW-2/USE-2/XLP MAX OD 0.17” (4.3mm) is the correct size and type for in-roadway modules, and activation mechanisms (bollards &/or Pushbuttons) for single run across street as recommended. Pull and cut 14 AWG wires to appropriate length. DO NOT STRIP INSULATION from IRWL wire. Connect to molded plug connector (pigtail cable assembly) provided in base plate assembly using provided Scotchlok Self-Stripping Pigtail Connectors-crimp to seal (see section 3.6). Activation mechanism conductors for push buttons or bollards (should be Belden cable 27601A as referenced in section 1.6) can be collocated in the same saw cut with the IRWL conductors. 3.2.9 SIGNAL HEAD INSTALLATION Using compressed air, remove dirt and all debris from base plate cavity. Ensure that mounting screw threads are clear. For extremely harsh environments, consider placing duct seal or plumbers putty onto the base plate in the region under the signal head around the outside edge perimeter to minimize the potential for moisture entering the base plate. Plug pig-tailed base plate cable electrical connector (RECEPTACLE) into IRWL cable electrical connector (PLUG). Note appropriate alignment for 3 pin connector. Ensure that mated molded plug connectors are PROPERLY SEATED. Check for proper “O” ring placement and attach IRWL to base using SOCKET HEAD CAP SCREWS with LOCK WASHERS and FLAT WASHERS. Tighten using an INCH POUND TORQUE WRENCH. Composite Base plate: Recommended torque value is not to exceed 4 ft lbs 48 in lbs (5N m) – NO TIGHTER. Hand tightening with a standard Allen wrench is also acceptable. WARNING – the composite base plate is very sensitive to this procedure, as damage to the threads may occur if tightened over 4 ft lbs (5N m). Check for even contact and snug fit with base plate top surface. Consider placing additional duct seal or plumbers putty into the gap between the base plate and the signal head and into the counter bore holes for the socket head cap screws to minimize the potential for moisture or debris from entering the base plate. Check for LED light module operation and move on to next unit. NOTE: It is IMPERATIVE that these steps be followed when installing the signal heads. Failure to do so voids the manufacturer’s warranty. It is highly recommended that within 30-45 days after initial installation, that the heads be re-checked to verify that the 4 ft lbs (5N m) of torque has been maintained. 3.2.10 NEW ROAD SURFACE CONSTRUCTION INSTALLATIONS If site is new construction, conduit under the roadway surface and knockout templates (to achieve base plate depression excavation for installation) is an option for the installer/contractor. This will avoid or minimize saw cutting into new roadway surfaces. Plywood cutouts or similar knockouts to match the base plate assembly size may be utilized in preparation for the installation of the base plates upon completion of the roadway surface. Precise engineering must to be exercised to insure proper placement and alignment of the in-roadway modules on the lane lines and travel lanes once the work is completed. A separate conduit is recommended for the single run of tray cable across the street. 3.3 CONCRETE INSTALLATION PROCEDURE The following information is a basic guideline for installing LightGuard Systems In-Roadway Warning Lights at locations where new concrete is to be poured. Conduit must be installed. It should be placed at least 3" to 4" (76mm to 101mm) below the surface of the roadway (or as required by local regulations). The single ¾” (19mm) hole in the center of the base Page 24 ® LightGuard Systems Installation & User Manual (all rights reserved) plate can be enlarged to approx. 2½” (63mm) dia in order to insert two ¾” PVC conduits connected to 90° elbows up into the base plate wiring cavity. Alternatively, a single 1½” to 2" diameter metal or PVC conduit can be used with a TEE connection stub that extends at least 1" (25mm) above the surface (after concrete is poured) for pulling wire loops through TEE’s. This is installed at each location where an In-Roadway Warning Light Base plate will be placed. Minimum recommended conduit is ¾” PVC to comply with NEC 14AWG type RHW-2/USE-2/XLP conductors. Use a circular wooden plug or equivalent 1½” (38mm) thick by approx 10⅛" (257mm) dia for SD-10 Base plate or 14" (355mm) dia for CHS-14 Base plate) with a center hole having a diameter just larger than the conduit stub(s) protruding up from the road bed as a concrete forming tool (ref section 3.2.6.1). The plug center hole diameter should be minimum 1/8” (3mm) smaller than center hole in base plate to ensure subsequent base plate seating. The plug is placed over the conduit stub (or elbows) during the concrete pour to create a depression form for installing the base plate when concrete is dry. After the concrete is dry, the wooden plug is removed & the base plate is affixed into the road (ref section 3.2). Excess concrete around the conduit should be removed to allow epoxy to bond the conduit to the base plate at the center hole. The extended conduit can then be cut flush to the inside surface of the base plate. Remove any excess epoxy &/or concrete from the base plate. After conductors are terminated, the exposed portion of the conduit opening should be filled with duct seal to minimize the potential of moisture or contaminants from entering the conduit. 3.4 IRWL SIGNAL AND BASE PLATE INSTALLATION GUIDELINES NOTE: Correct Placement of Bases is CRITICAL to System Performance Step 1 - Determine placement and site angles of in-roadway warning signals to intersect at optimum driver viewing zone as specified by Signal Alignment Drawing (See Section 3.7.1). Signal assemblies can be manually aimed, but laser site method is optimal. Step 2 - Perform saw cuts using pavement cutting device in accordance with predetermined layout to facilitate hook-ups through bottom of base plate to terminal connection points. Cuts should be ½” (12mm) wide in accordance with the CA Standard Plan ES-5A, or local standards, with a depth of 2” to 2½” (50mm to 63mm) for direct burial of wire (see Sections 3.5.1 and 3.5.2). Step 3 - Provide depression cut-out for base plates approximately 1 3/8” (35mm) ± 1/8” (3mm) deep on concrete or asphalt. Depression cut-out should be ¼” to ½” (6mm to 12mm), slightly larger than base plate. Depression cut-outs should be level, or even, to conform to the existing approach grade of the roadway. Step 4 - If required, dig out for traffic electric hand hole boxes and install boxes for wiring access points at predetermined locations in accordance with the CA Standard Plan ES-5E, or local standards. Step 5 - Install all necessary wire to predetermined connection points and lay in cleared roadway cuts. Using duct seal or equivalent, create a temporary “epoxy dam” section 3.5.3 at the interface where the saw cuts enter/exit the depression cut area. The epoxy dam will temporarily hold down the wires & simultaneously dam the core drill area to prevent flow of epoxy back into the saw cut. Step 6 - Check for proper site distance angles and level depth of base plate (See Sections 3.7, 3.5 and 3.2.4). Mark alignment on roadway for base plate focus direction. Top of base plate (circumferential edge shown in section 3.5.1) should be flush or slightly below (less than .10” = 2.5mm) roadway surface AND free from excess adhesive (See section 3.5). Step 7 - Mix only enough 2-part epoxy (BONDO 7084) for 2 to 3 base plates, since Epoxy working life is approximately 10 minutes. Surfaces should be cleaned of dirt or debris, and dry before applying adhesive. Ensure that wires are vertical in the center of the depression cut. Pour epoxy into Page 25 ® LightGuard Systems Installation & User Manual (all rights reserved) depression cut approximately ¼” (6mm) depth. Pull wire through center hole in base plate. Secure base plates to roadway surface by pressing the base plate into the epoxy in the depression cut. Ensure that epoxy flows around the outside diameter of the base plate and slightly around the wires emerging from the center hole of the base plate, but DOES NOT fill the base plate. Ensure that epoxy fills outside diameter of base plate up to grade level. Ensure that the base plate is aligned with the mark made in step 6 above (See section 3.5) and is aimed vertically toward the zone of convergence prior to epoxy curing. Allow minimum of 30 minutes of epoxy cure time prior to moving wires for connecting pigtail gel plugs (section. 3.6). Step 8 - Allow minimum of 1 hour cure time (above 70°F & 2 hours if colder temperatures) before opening traffic lanes to vehicles travelling over recently epoxied base plates. Signal heads can be secured to base plates as soon as epoxy has sufficiently hardened. NOTE: Temperature is critical. Step 9 - Secure in-roadway warning signal to base plates using socket head cap screws using Allen Wrench or equivalent. Socket head cap screws are to be coated with anti-seize compound for maintenance purposes to ensure that screws can be removed after exposure to the environment & additionally contain an embedded nylon thread-lock bead to prevent the screws from backing out while exposed to the roadway environment. Step 10 - Complete “dress-up” saw cuts with Loop Sealant etc. DO NOT use Loop Sealant to “dress up” outside diameter of base plate to level epoxy surface with grade. 3.5 3.5.1 IRWL SAW CUT CROSS-SECTION DIAGRAMS FRONT VIEW - PARALLEL TO ROADWAY (SD10-C BASE PLATE SHOWN) IN-ROADWAY WARNING SIGNAL 1½” (38mm) WIRE 2½” (63mm) FINISHED GRADE OFPAVEMENT PAVEMENT BOTTOM OF SAWCUT 3.5.2 LOOP SEALANT EPOXY AROUND BASEPLATE SIDE VIEW - PERPENDICULAR TO ROADWAY FINISHED GRADE OF PAVEMENT DRAWING NOT TO SCALE In-roadway warning signal 2 ½” in MAX.

This can only be done in baseplates that have enough wire extending from the roadway to allow the IRWL pigtail to set into the underside of the IRWL connector cavity when assembled. The GEL PLUG connector requires 3/4" (19mm) of wire to be fully inserted into it. 1) Outer Diameter of type RHW-2/USE-2/XLP wire should be MAX OD 0.17” (4.3mm). This will allow the insulated wire to be inserted into the Scotchlok 314 connector. Any exposed bare wire should be clipped off from the wires when connected to ensure that no part of the conductor is exposed. 2) Insert all three wires to be connected into the three open holes in the connector, until they all reach the back end of the connector. End of Insulated wire should touch back of connector 3) With a standard pair of slip joint pliers, pinch down on the blue cap of the connector until the outer edge of the blue cap is flush with the rim of the white connector housing. It may be necessary to wipe off the expelled gel after crimping. Flush after crimping 4) Place the connector in the bottom (lowest part) of the base cavity and route the wires so no pinches will occur when the head is tightened. Double-sided adhesive tape can be used to hold connector in place until head is re-installed. 5) Plug IRWL into connector and fit IRWL into base. Adjust wires so NO PINCHES occur.

Using the chart showing the Minimum Stopping Distance on Dry Pavement, determine the total stopping distance based upon the speed limit of the roadway. The minimum starting point of the convergence zone is determined by the minimum stopping distance on dry pavement for the posted speed limit. This minimum stopping distance includes a motorist decision distance, based on a onesecond reaction time, plus the necessary speed deceleration distance required to come to a complete stop under optimum conditions. As an example, the minimum stopping distance on dry pavement for a roadway with a 35 mph (56Kmh) speed limit is approximately 161 ft. (49m). This minimum distance would allow a motorist to visually recognize the flashing amber LED lights, slow down, and if necessary, bring his/her vehicle to a complete, safe stop. Signal heads should be aligned to make the LED lights and therefore the zone appear as soon as possible as the driver approaches. On curved or winding roads, the entrance to the zone isn’t always at the optimal distance to provide the earliest possible notification to approaching vehicles. Optional LED signal heads may also be installed down the center line of the road to give even more advance warning, giving the driver time to brake and stop for the pedestrian.

Each bollard contains sensor circuitry, and they are placed so pedestrians entering a crosswalk must pass between them automatically activating the Smart Crosswalk™. The built-in sensors detect pedestrians using the crosswalk and detect their direction of travel. The built-in sensor module projects infrared beams of modulated light to the respective receiver module. Each module incorporates a high gain detector. This allows the System to activate for Crosswalk entry, and not for exit. 4.2 BOLLARD DRAWING GRILLED FACE PLATE covers LED lighting panel Ball Socket Alignment Access The Top By Removing Grilled Face Plate & Dome Housing WIRING TERMINAL BLOCK CONNECTIONS LOCATED ON BACK SIDE OF PANEL SPECIFICATIONS SIZE: COLOR: MATERIAL: DETECTION METHOD: RATING: DISTANCE: OPERATING TEMPERATURE: Height: 42” (1067mm) Diameter: 8½” (216mm) White (standard) Extruded Aluminum Body with Cast Top Break Beam Modulated at 880 nm 12.5 volts DC (not to exceed 15 V) Not to Exceed 50 feet between Bollards -20° C to +70° C Humidity 90% at 50° C (non-condensing) Page 31 ® LightGuard Systems Installation & User Manual (all rights reserved) 4.3. BOLLARD INSTALLATION GUIDELINES 4.3.1. INSTALLATION STEPS Step 1 Prior to installing bollards, the proposed site should be inspected several times to observe the everyday habits of local citizens who utilize the crosswalk. Particular attention should be paid to how far back pedestrians may “cut the corner” when entering the crosswalk. Bollards, as positioned, may not detect every pedestrian using the crosswalk. For example, a 12 ft. (3.6m) wide crosswalk (dimension from outside crosswalk stripe to outside crosswalk stripe), bollards would be positioned approximately 5 to 6 ft. (1.5m to 1.8m) outside of the outer edge of the crosswalk stripe and about 18” to 24” (46cm to 61cm) behind the face of curb. Once bollard locations have been determined, wiring, or conduit, may be run prior to installation of the hold down bolts (See Section 4.3.2). Step 2 The preferred method of securing bollards into position is to remove an 8” (20cm) square section of sidewalk then dig approximately 18” (46cm) and set anchor bolts in 6 sack concrete mix ( Refer to Bollard Mounting Detail Section 4.3.4). Other methods are acceptable, such as drilled anchor bolts, however, the bolts may become loose as a result of the bollard being bumped. A loose bollard will cause the calibrated internal sensors to become misaligned (reference section 4.5.1 for alignment). J-Bolt alignment template is provided. Snap a “chaulk line” between bollard pair locations to ensure that j-bolt templates are directly facing each other (not skewed). Step 3 After bollard anchor bolts have been set, and the concrete has cured, the bollards can be secured to the anchor bolts. Position the base of the bollard approximately 1/8” to ¼” (3mm to 6mm) above the finished sidewalk grade, level, and secure. All hardware MUST be tightly secured. If installed on a sloping sidewalk, ensure that bollard is vertical using leveling nuts. Step 4 Run wires and make final wiring connections to each bollard (See Section 4.2). Make wiring connections to terminal blocks in enclosure (See Section 4.3.2). Once wiring connections have been completed the bollard light sensors are ready to be aligned (See Sections 4.5). 4.3.2 SAMPLE BOLLARD LAYOUT AND WIRING DIAGRAM Bollard 2-A NOTE: Always use 8 conductor 18 AWG signal cable for single run connections between bollards or pushbuttons from enclosure to opposite side of street (shown as bold dashed line in diagram) Bollard 1-B BR BE AR AE FROM BOLLARD 2-A TO 2-B, YELLOW, BROWN, & BLUE WIRING NOT NEEDED FROM BOLLARD 1-A TO 1-B, YELLOW WIRING NOT NEEDED AE AR BE BR Separate wider than crosswalk ENCLOSURE NOTE: Bollard 2-B AE= A EMITTER & AR= A RECEIVER BE= B EMITTER & BR= B RECEIVER. 18” MINIMUM DRAWING NOT TO SCALE Page 32 Bollard 1-A 1-B ® LightGuard Systems Installation & User Manual (all rights reserved) Refer to section 3.7.1 & 3.7.2 for IRWL Aiming and Alignment 4.3.3 BOLLARD WIRING TERMINAL BLOCK CONNECTIONS ENCLOSURE TERMINAL BLOCK CONNECTIONS FOR BOLLARDS: 4.3.4 1 1 2 2 P P S S B A B A B A B + + + B G G G G + N N N N D D D D Y E L L O W R E D B R O W N B L U E O R A N G E B L A C K BOLLARD MOUNTING DIAGRAM NOTE 5.5” dia Bolt Circle Template(3 @ 120°) furnished by LightGuard Systems NOTE: To alleviate wire access or electrical connection difficulties, conduit height should not exceed 1” above grade – unless required by local regulations Page 33 ® LightGuard Systems Installation & User Manual (all rights reserved) 4.4 BOLLARD SENSOR ADJUSTMENT Each bollard is equipped with detection sensors 1 transmitter/emitter and 1 receiver (See Section 4.3.1). To adjust the detection sensors follow the procedure below; Step 1 Remove upper frosted glass grilled faceplate on bollard 1-A, located near enclosure (See Section 4.2 & Figure 4-5) Step 2 Remove 2 counter sunk Allen screws at the bottom of frosted glass opening. Step 3 Disconnect Brown & Blue terminal block wires from lighted window panel (courtesy light LED). Step 4 Slide rounded top of bollard (Light Dome Assy) upward and out. Step 5 Standing behind the bollard, look down 18” (45cm) into the top portion of Bollard 1-A. There are 2 black colored sensor modules. The sensor on the right is the Zone receiver and the sensor on the left is the Zone emitter (See section 4.3.1 & Figure 4-5). Step 6 With PCU enclosure door open, observe the 2 rows of Activation LED indicators immediately below, and slightly to the right of, the PCU keypad (See Section 2.5.1, pg. 8). Starting from left, to right, the first yellow upper LED is Zone 1A, and the green LED immediately below is Zone 1B, and the second yellow upper LED is Zone 2A, and the second green LED immediately below is Zone 2B. (Note: some older model PCUs may have all green LED indicators lights). When one of the Activation LED’s is illuminated, the power control unit (PCU) has been signaled that an object has entered the activation zone. Once sensor A is triggered, followed by sensor B, the system is activated for the desired cross time. If an Activation LED is illuminated but no object has entered the activation zone, then the receiver is not receiving the emitter’s beam (See note below, this page) Step 7 Repeat above procedure for bollards 1-B, 2-A, and 2-B. Note that standing behind each bollard, the emitter is always on left side and receiver is always on right side. 4.5. BOLLARD ALIGNMENT After following steps in Section 4.4, if any activation LEDs in the PCU are illuminated, this indicates bollard detection sensors are out of alignment. To adjust alignment of the bollards refer to Section 4.5.1, and follow the procedure below: Step 1 - Determine that bollards 1A and 1B are plumb, and aimed directly at each other. If the bollards are not aimed directly at each other, then align sensors following steps in Section 4.4 above to compensate for bollard misalignment. Step 2 - Make sure bollard piezo-electric buzzer at bottom of bollard is temporarily connected with red wire to + and black to S. If the sensor is not aligned the buzzer will sound. Step 3 - Ensure there is power to emitting sensor in each bollard, (when standing in behind the bollard the emitter is on the left side). If there appears to be a power problem, correct then continue. Step 4 - Adjust a bollard’s receiver and emitter sensors by 1) loosening screws on each side of sensor and move sensor until piezo buzzer siliences. When properly aligned, each Activation LED indicator in the PCU will NOT be lit and the piezo will NOT sound which means that both detection zones are clear and ready for operation. 2) Tighten sensor screws when properly aligned and disconnect piezo. If Buzzers are not disconnected after alignment, then each time the Bollard Beam is “broken” the buzzer will sound momentarily. The LightGuard System is supplied with a portable mirror (located in electrical Page 34 ® LightGuard Systems Installation & User Manual (all rights reserved) cabinet) that can be used to view the LED status Indicators located on the back side of each of the bollard sensors. (Refer to Figure 4-5). Under normal operation; 1) the emitter/transmitter LED Status indication will be green, 2) the receiver LED Status Indication will be green only when partially aligned, both green and orange when perfectly aligned, and yellow only when the light beam is broken (not receiving signal from emitter). If an LED status Indication is Orange, the sensor is shorted and requires troubleshooting. Follow above Steps 1 through 4 for bollards 2A and 2B. Once bollards 2A and 2B are aligned, and reassembled, ensure that all Activation LED indicators (2 rows of LED’s immediately below the PCU keypad), are not lit (See Section 2.5). Reassemble the bollards by reversing Steps 1 through 7, of Section 4.3.1 Emitter Receiver Standing behind Bollard & looking Down, Emitter is on the Left, Receiver is on the Right Remove Grille, Wires, & Light Dome Assy LED Status Indicators To adjust sensor orientation/alignment, LOOSEN these screws only, DO NOT remove screws.

Step 2 Observe pedestrian entering the crosswalk between the bollards. The first LED that lights should be yellow (PCU upper row is A zone), the second should be green (PCU lower row is Bzone - lower rows are green in some PCUs). If the LED’s illuminate in the reverse order, then the wires are reversed. To correct, reverse wires 1A and 1B at the PCU terminal block connections. Step 3 Observe pedestrian exiting the crosswalk. The activation LED indicators should light in order of Zone 2B, then Zone 2A. In this condition, the PCU will ignore the call signal and not initiate the flashing sequence. Step 4 Observe pedestrian returning from other side of street entering the crosswalk between bollards 2A and 2B. Ensure that when pedestrian enters the crosswalk between bollards that the 2A Activation LED (yellow) comes on, then the 2B Activation LED (green) comes on.

Both contain a courtesy light. The difference between the standard Bollard and the Uni-Bollard is that the Uni-Bollard contains 2 receivers instead of a receiver/transmitter pair. The Uni-Bollard is designed to be installed with an ISAD (which contains at least 1 broad beam width transmitter). Each Uni-Bollard is required to have 4 conductors – (1) 12VDC, (2) Switch wires, & (1) ground. The switch wires are terminated in the control panel in the manner described in section 4.3.2. Access to the Uni-Bollard sensors is identical to the procedure noted in section 4.2. Electrical connections are made to clearly marked terminal posts located inside the Uni-Bollard The ISAD installs in the pavement in the identical manner as an In-Roadway Warning Signal shown in section 3. The recommended maximum distance between the Uni-Bollard & the ISAD for reliable operation is 25 ft. (7m). 4.7.1 UNI-BOLLARD CONFIGURATION DIAGRAM Uni-Bollard Sensor Locations Infrared Light Beams WIRING TO CONTROLLER WIRING BETWEEN ISAD & UNIBOLLARD ISAD FOCUS PARALLEL to BOLLARD FACE Page 37 ® LightGuard Systems Installation & User Manual (all rights reserved) 4.7.2 EXAMPLE UNI-BOLLARD INSTALLATION DIAGRAM Typical Uni-Bollard installations are arranged with an ISAD installed in the roadway & a Uni-Bollard installed on the sidewalk. The drawing below depicts example locations for field installation. 4.7.3 • • • • ISAD PLACEMENT & CONSIDERATIONS The ISAD should not be placed such that Direct Sunlight is focused into the face of the ISAD. This could degrade activation reliability The ISAD should not be placed in the roadway such that debris or Water can “build up” on the face. This will cause excessive field maintenance. The ISAD should be placed relatively close to the curb (not in the flow of traffic). If the ISAD is placed in the flow of traffic, this will induce nuisance (false) activations of the crosswalk warning system. The ISAD must be oriented such that it is facing directly parallel to the Uni-Bollard (refer to figure in section 4.7.1) & is relatively level with the roadway. However the ISAD may require tilting to ensure that the transmitters in the ISAD are pointed at the Uni-bollard sensor locations. The Uni-Bollard sensors are used to effect the ISAD alignment. Page 38 ® LightGuard Systems Installation & User Manual (all rights reserved) 4.7.4 UNI-BOLLARD WIRING DIAGRAM The following diagram illustrates how to connect a Uni-Bollard & ISAD to the LGS controller cabinet. The ISAD is powered from the B+ and GND terminals. The crosswalk entrance side of the Uni-Bollard is connected to either 1A or 2A. The crosswalk exit side of the Uni-Bollard is connected to either 1B or 2B. 4.7.5 UNI-BOLLARD SENSOR ADJUSTMENT The ISAD cannot be adjusted in the field. Only the Uni-Bollard can be aligned to the ISAD after installation. The Uni-Bollard sensors are adjusted as described in section 4.4. The audible buzzer in the Uni-Bollard is attached to one sensor for alignment & then subsequently disconnected. The audible buzzer is then attached to the other sensor for alignment & then subsequently disconnected. Page 39 ® LightGuard Systems Installation & User Manual (all rights reserved) 5 5.1 PUSH BUTTON ACTIVATION MANUAL PUSH BUTTON ACTIVATION DESCRIPTION Manual installations utilize a standard pedestrian operated push button assembly to activate the system. In these installations, a pole mounted control box containing the push button, a small sign with the words “CROSS WITH CAUTION”, and a row of 4 flashing amber LEDs, as shown below, is placed near the entrance to crosswalk (refer to section 3.6.2). The row of 4 flashing, amber, LEDs indicates to the pedestrian the warning system is activated. The words “CROSS WITH CAUTION” remind the pedestrian to maintain vigilance for their own safety by paying attention to traffic conditions while crossing the street.

These signs are placed at, or before, the crosswalk to assist in warning approaching motorists that a pedestrian is in, or about to enter the crosswalk. The embedded LED modules flash at the LightGuard System® enhanced flash rate. This LED “enhanced” pedestrian crossing symbol sign should be installed at the crosswalk location as recommended in the Manual on Uniform Traffic Control Devices (MUTCD) to replace the standard yellow W54 sign. For school crossings, a W66 or W-63 type (S2-1 or S-2-1 in FYG) school symbol sign also available.

Use the ¼” hardware to attach the module to the Module Rails. Use the 5/16” hardware to bolt the Module Rails to the SPM-1 Pole Bracket. Adjust the mount to the proper tilt angle for your site latitude. Face the solar module due South (NOT MAGNETIC SOUTH) for Northern Latitudes and due North for Southern Latitudes. ENSURE that the Batteries are fully charged prior to installation. SOLAR MODULE Use the 14 / 2 TC tray cable supplied to wire the solar module into the charge control panel inside the enclosure. It is recommended that ½” flexible metal conduit be run between the solar module junction box and the mast to protect the tray cable. An opening in the mast to accept the conduit will need to be provided. Remove the cover of the black junction box on the back of the module and note the 6 screws. Also, note a positive (+) sign and a negative (-) sign which show the 2 positive and negative terminals. Connect 1 wire to either of the 2 positive (+) and negative (-) terminals. Use the red conductor for positive and the black for negative. Do not use either of the 2 screws in the middle, these screws are not electrically connected to the module circuit. Route the tray cable down the mast into the enclosure. Make sure the solar module is covered, or not connected to the tray cable, when routing the cable through the enclosure. Even in low sunlight the module can produce 18 to 20 volts. 7.2.1 SOLAR MODULE DESCRIPTION The solar array consists of a minimum 75 watt solar power module which is to be pole mounted. This solar module is designed to charge the two 12 volt batteries in the system. In full sun, this module can produce a maximum on 4.25 amps when charging the battery. During the day, the amount of charging current will vary with the intensity of the sunlight hitting the module. The open circuit voltage (voltage when not connected to charging circuit) can be up to 21 volts. 7.2.2 SOLAR MODULE MOUNTING The solar module is to be mounted to the side of a 4” galvanized mast using the aluminum side-of-pole mount and hardware supplied. The solar module must be oriented facing TRUE South . Attach the mounting rails to the pole bracket and adjust the tilt angle to create an angle setting for your local latitude from horizontal facing South. Refer to sections 7.2.3 & 7.2.4 for orientation details. Use U-bolts to secure the mount to the mast Page 43 ® LightGuard Systems Installation & User Manual (all rights reserved) Instructions for SOLAR PANEL MOUNT, model #HPMH-50/90, side-of-pole mounting kit: PARTS LIST Part Qty SPM-1 Module Rail 1/4-20X3/4” SS Bolt 1/4-20 SS Flat Washer 1/4-20 SS Lock Washer 1/4-20 SS Nut 5/16-18 x 1” SS Bolt 5/16-18 SS Flat Washer 5/16-18 SS Lock Washer 5/16-18 SS Nut 4” Hose Clamp 4” U-Bolt 1 2 4 4 4 4 4 8 4 4 2 1 Solar Panel Terminal Block Electrical Connections: POSITIVE to Terminal 0 NEGATIVE to Terminal 6 7.2.3 ORIENTING THE SOLAR MODULE The following information was authored by www.powerupco.com & is reprinted herein without permission It is important for proper system operation that the array be oriented true South (if you are located in the northern hemisphere). The directions of magnetic South and true South differ from one another depending on geographic location. This variance is called declination. Check the deviation for your region in order to extrapolate true South from a compass heading of magnetic South. The map in this section shows the magnetic declination for the US. For example, central Oklahoma falls between the 8° E and the 10° E lines. This means that the north point of a compass points about 9° E of true north. So true north is actually 9° to the WEST of where the compass points 7.2.4 DECLINATION ANGLE FOR SOLAR PANELS The following information was authored by http://www.oksolar.com/ and is reprinted herein without permission When installing photovoltaic modules, be aware that they generate maximum power when facing the sun directly. The fixed position which approximates this ideal over the course of the year, thus maximizing annual energy production, is facing due South (in the Northern Hemisphere) or due North (in the Southern Hemisphere) at the angle listed in the table in the next column. Note that these orientations are true, The table below shows the fixed angle above horizontal at which modules should be installed in order to maximize annual energy output. At some installations, it may be cost-effective to adjust the tilt seasonally. At most latitudes, performance can be improved during the summer by using an angle flatter than the chart’s recommendation; conversely, a steeper angle can improve winter performance. If modules are not cleaned regularly, it is recommended that they not be mounted at an angle flatter than 15°. Flatter angles cannot take full advantage of the cleansing action of rainfall. Page 44 ® LightGuard Systems Installation & User Manual (all rights reserved) 7.2.5 MODULE TILT ANGLE Solar modules produce the most power when they are pointed directly at the sun. For installations where the solar modules are mounted to a permanent structure, the solar modules should be tilted for optimum winter performance. As a rule, if the system power production is adequate in the winter, it will be satisfactory during the rest of the year. The module tilt angle is measured between the solar modules and the ground. Example: A module mounted in Miami, Florida (latitude 26º should be tilted at approximately 31º from horizontal, and should be faced due South. Latitude Site 0-15° 15-25° 25-30° 30-35° 35-40° 40° + 7.3 Tilt Angle 15º SAME AS Latitude add 5° to local latitude add 10° to local latitude add 15° to local latitude add 20° to local latitude SOLAR SYSTEM BATTERIES The enclosure contains 2 SLA batteries, the PCU (power control unit) and the charge controller. Two 12 volt deep cycle sealed gel-cell batteries are supplied. Each battery is rated at approximately 100 amp hours. The batteries are to be wired in parallel (positive-to-positive and negative-to-negative) to give 12 volts nominal at 200 amp hours of storage. Use the red and black battery cables supplied to parallel the batteries. Install the wiring into the terminal blocks & circuit breaker before installing the batteries. Page 45 ® LightGuard Systems Installation & User Manual (all rights reserved) Use the red and black cables, supplied with the ring terminals, to make the battery connections. Connect the red cable to the positive post on 1 battery and the black cable to the negative post on the other battery. This will ensure even charging between the 2 batteries (note figure below). + - Battery 1 Battery 2 Connect the red and black #14 tray cable wires, from the solar module, to the labeled circuit breaker and negative buss block (refer to Section 2.4.3). 7.4 7.4.1 CHARGE CONTROLER CHARGE CONTROLLER WIRING The charge controller, located inside the enclosure, provides all wiring connections for the solar module, batteries, and power to the PCU. The PCU controls power to the in-roadway warning signals, signs, and push buttons. Ensure all circuit breakers are OFF before making any connections. There are three 15 amp circuit breakers: 1) 2) 3) 7.4.2 Solar Module circuit breaker; controls power from the solar module. Load circuit breaker; controls load power to the PCU, in-roadway warning signals, and signs. Battery Main circuit breaker; controls battery power to the system. SOLAR CONTROLLER A charge / load controller is located on the charge control panel (for further information / specs, contact your LGS representative). This controller is being used to regulate the battery charging and protect the batteries from being over discharged. The charge controller is pre-wired and factory adjusted. Do not make any adjustments to the charge controller without contacting LightGuard Systems, Inc. first. Indicator(s) on the face of the controller indicates the battery state of charge. Note the legend on the face of the charge controller. During normal operation, the charge controller will allow the battery voltage to rise up the approximately 14.1 volts while charging. This end-of-charge voltage will vary with temperature. The charge controller might employ a supplemental temperature probe attached to the side of one of the batteries in the enclosure. If supplied, attach the probe approximately three quarters of the way up the side of the battery case using the adhesive pad on the probe. This will ensure proper charging of the batteries throughout the year. At night, the battery voltage should register between 12.0 and 12.8 volts depending upon how well the batteries were charge during the day. In times of exceptionally bad weather, and / or exceptionally heavy crosswalk usage, the battery voltage may drop below 12.0 volts. When the voltage drops to below approximately 11.8 volts, the charge controller will shut off power to the PCU and in-roadway warning signals ensuring protection of the batteries from damage as a result of over discharge. The charge controller will not allow power back to the PCU until the voltage rises back up to approximately 12.8 volts after several hours of charging.

Check push buttons connections. If LED Indicator does not flash, check PCU components. Check all in-roadway warning signals for damage Remove & Replace (R & R) with spare warning signal as needed. Check all in-roadway warning signal window ramps for blockage or debris. Broom any debris from pavement around in-roadway warning signals to allow for unobstructed motorist viewability. Check all in-roadway warning signal light modules for proper flash operation View in-roadway warning signals from 150' to 200' away for the approaching motorists' perspective.R & R with spare warning signal as needed. Insure that enclosure components are operational Shut off power to PCU via circuit breakers and disconnect battery. Check battery voltage. Load test battery 3-4 AMP. Tighten wire connections, and/or remove, and look for corrosion and retighten. Perform a wire push/pull test to verify wires are firmly installed. Power up PCU with battery only. Check voltage at battery to assure that battery has minimum of 12.5 Volts. Document counters and log date, time of service, and name of personnel repairs. List any repair findings. Secure system door. GRAFFITI OR PAINT ON BOLLARDS OR ENCLOSURE EQUIPMENT Check for proper activation operation Remove graffiti or paint. Tagster Graffiti Emulsifier from Rhomar Industries is recommended. Call (800) 688-6221to order. SYSTEM ON CONSTANT BLINK * PCU FLASHING 50/50 Check for stuck PB or misAligned Bollards ref section 4.4 PUSH BUTTON INPUTS DO NOT ACTIVATE FLASHING OUTPUT Verify that button(s) is/are operational. Verify conductor integrity from push buttons to flashing controller IN-ROADWAY WARNING SIGNALS FLASHING DIMLY, OR NOT AT ALL • • • • • • • • • Inspect PCU display for diagnostic information. System enters “Default Flash Pattern” to alert maintenance crews that attention is required. If the LCD does not indicate which input is “stuck”, then press “D” on the keypad to display input diagnostics. Inputs can be simulated at the flashing controller. Temporarily remove the button input field wires from the Din Rail locations PA/PB& affix a jumper wire (12” stripped ½” at both ends) into the DC GROUND on the Din Rail. Then use the “free end” of the jumper to make contact with the PA/PB inputs on the flashing controller. If an LED indicator illuminates, then the PCU can receive signals & the problem is with the field wiring or the Push Button(s) Routine maintenance should include periodic on-site inspections of the System for proper operation. Check activation system for proper operation and tighten fastening hardware as needed. Clean bollards and sensor shield if needed and check for proper bollard alignment and activation. In-roadway warning signals should be visually checked for sufficient light output with window ramps swiped clean as needed. Should window ramp become obscured over time, remove and replace with spare warning signal. Check for proper adhesion of all warning signals to the roadway surface. Fill any gaps around inroadway signal assemblies with bituminous hot stick to prevent debris or moisture intrusion. Inspect wire trench cuts for sufficient loop sealant and fill where needed with filler or bituminous hot stick material. Check enclosure and sign mounts for secure attachment and tighten fastening hardware as needed. Note/Record activation counts using PCU keypad functions 1, 2, or 3, then reset to clear by pressing 0, then 555 (NOT MANDITORY) Note and clean any graffiti from enclosure equipment.

Installation should consist of all components secured appropriately and all electrical connections terminated as required. Step 1 Energize all circuit breakers Step 2 Contact LightGuard Systems to obtain a 3 digit ACTIVATION CODE for warranty & maintenance tracking purposes. (888) 247-2974 Step 3 Verify that no LED fault/activation indicators are ON in the PCU. These indicators are 2 rows of LED (Yellow & Green) directly below the PCU housing in the enclosure. If any fault/activation indicators are on, check Bollard alignment, push buttons, and field wiring connections. Step 4 Press keypad 9 to initiate constant blink. Verify that all IRWL & optional illuminated LED signs & Push Buttons are active Step 5 Press keypad 9 to toggle constant blink off Step 6 Test/verify that activation mechanisms operate (PB &/or Bollards) and activate flashing output for the cross time duration. If any Bollards activate the system when exiting the crosswalk instead of entering the crosswalk, swap A & B wires in control panel for that Bollard pair. Step 7 Set cross time as required (refer to section 2.8.3) 8.3 FIELD RELATED TOTAL PREVENTATIVE MAINTENANCE 8.3.1 SCOPE This procedure describes the recommended process for inspecting & maintaining LGS equipment after installation. This section applies to Illuminated signs, electrical interface cabinets, In Roadway Warning Lights (IRWL), and activation mechanisms (Bollards & Push Buttons). 8.3.2 MAINTENANCE PERIOD Perform Preventative Maintenance/Inspection approximately every 6 months. 8.3.3 MATERIAL REQUIRED A.
